Web of Trust : FrontEnd.

@oalders : I pushed a few commits yesterday. The work is still in progress on the metacpan-web frontend.
I'll keep pushing the changes.

Thanks!
Since Catalyst is all Moose-based, this should be
`extends 'MetaCPAN::Web::Controller'`
rather than `use base`.

Actually all of the other controllers use this pattern:
`BEGIN { extends 'MetaCPAN::Web::Controller' }`
